Value-based payment for providers is often predicated on being able to measure physician quality with a single composite measures. For instance, Medicare’ s Value-Based Payment Modifier (Value Modifier) combines a variety of individual quality metrics across domains to create a single quality score. Payment to physicians is adjusted based on a combination of physician quality and resource use.
The question remains, however, whether these composite scores do a good job of measuring quality. Martsolf, Carle, and Scanlon (2017) notes that this may not always be the case.
